i have just done a top end rebuild on a 2004 1.3 el daihatsu sirion. new valves, valve stem oil seals and gaskets, when the engine was put back together a pressure test was done and there was 180 psi across all 4 bores, so the pistons was fine. when the car was started it was ok for the first few minutes then started smoking blue white smoke, not just a little bit but PLUMES of it. i removed the cat/manifold and started the car again and there was lots of oil coming from all four exhaust ports as soon as it started. the head is straight, no cracks, all torqued down correctly, and gasket on as it should be. i am now totally baffled as to why there is this much oil escaping into the bores and coming out of all 4 exhaust ports. ANY HELP WILL BE VERY MUCH APPRECIATED THANKS.
